The Girl Scouts of America are celebrating their 100th anniversary this year and, to mark the occasion, have introduced a brand new cookieto the Girl Scout cookie lineup: Savannah Smiles. Savannah Smiles are sugar-dusted, lemon flavored cookies that are described as being “cool and crisp, with just the right number of lemon chips to deliver tiny bursts of flavor.” They look and sound very similar to a Lemon Coolers, a cookie that the Girl Scouts featured a few years back but have since discontinued, which were very popular because they were zesty and quite different from the rest of the cookie lineup.

It is worth noting that the Savannah Smiles do not contain any partially hydrogenated oils, as per their ingredient list, and that many of the other Girl Scout cookies have also eliminated partially hydrogenated oils. Thin Mints and Samoas still include them, however.

Most girl scouts will start taking preorders for cookies within the next couple of weeks, and you’ll probably start seeing girls “boothing” outside local markets starting next month. The rest of the cookie lineup includes Thin Mints, Samoas, Tagalongs, Do-Si-Dos, Trefoils, Dulce de Leche and Thank You Berry Munch.
